Katyayana Sutra
Kātyāyana was a disciple of Gautama Buddha.
He was born in a Brahmin family at Ujjayini (Ujjain) and received a classical Brahminical education studying the Vedas.
Tradition attributes to Katyāyana the authorship of two late Pāli canonical texts Nettipakarana, a commentary on Buddhist doctrine; and peṭakopadesa, a treatise on exegetical methodology.
In Sanskrit his name is Kātyāyana (कात्यायन) or Mahākātyāyana (महाकात्यायन); in Pāli Kaccāna (or Kaccāyana), or Mahākaccāna; and in Japanese 迦旃延 Kasennen.
Katyayana (Skt. Kātyāyana) — one of the principle disciples of Buddha Shakyamuni who wrote down one section of the Abhidharma.
Kātyāyana (c. 3rd century BC) was a Sanskrit grammarian, mathematician and Vedic priest who lived in ancient India.
He is known for two works:
The Varttika, an elaboration on Pāṇini grammar. Along with the Mahābhāsya of Patañjali, this text became a core part of the Vyākarana (grammar) canon.
He also composed one of the later Sulba Sutras, a series of nine texts on the geometry of altar constructions, dealing with rectangles, right-sided triangles, rhombuses, etc.
Kātyāyana's views on the word-meaning connection tended towards naturalism. Kātyāyana believed, like Plato, that the word-meaning relationship was not a result of human convention.
For Kātyāyana, word-meaning relations were siddha, given to us, eternal.
Though the object a word is referring to is non-eternal, the substance of its meaning, like a lump of gold used to make different ornaments, remains undistorted, and is therefore permanent.
